中文摘要 | 全陶瓷�G復體雖然早在 1886 年就由 C.H.Land 所提出,但是受到強度不夠,密 合度不佳的限制,臨床上並未受到太多重視。1965 年 McLean 及 Huges 在陶瓷中加入氧化 鋁顆粒,提出了強度較傳統長石陶瓷為強的瓷套冠 (porcelain jacket crown); 這三十年 來於全陶瓷�G復體的不斷研究改進,全瓷冠在強度及精密度上都有長足的進步,此外,它良 好透光性所呈現的自然色澤更符合了追求美觀性的牙科技術潮流,所以全陶瓷�G復體在目前 固定�G復體中,已占有一席之地位。1985 年由 Vita 公司上市的一套全瓷系統 "In-Ceram" ,此系統在現有的市場上,號稱是所有全瓷牙冠中曲張強度最強,密合度最高,透光性及美 觀性最好的,而且在許多歐洲國家逐漸被廣為運用。故本文除了回顧學者提出的一些全陶瓷 系統外,並針對 Vita-Ceram 系統做一介紹。 |
英文摘要 | In spite of the ceramic material was introduced to dentistry, early in 1886, the inferior physical properties have limited the use of ceramic materials. In 1964, McLean and Hughes reinforced ceramic with aluminum oxide. The process allowed the development of aluminous porcelain crowns, which was stronger than previons types, but the long-term failure rate was still not clinically acceptable. In the mid-1980s, the all ceramic restorations were reborn. This may be because of the interest in "esthetic dentisty" and the advancement in biomaterial research. Besides esthetics, the most important property of these new all-ceramic systems was improved in strength. Castable ceramics and other high-strength ceramics were available by the inducement of crystallization or the addition of oxides. Although ther were varying degrees of clinical success, more all-ceramic restorations (eg. inlay, onlay, veneer, crown, FPD) were applied in prosthetic dentistry. Vita In-Ceram system, a glass-infiltrated aluminum oxide ceramic, was developed by Dr. Sadoun in 1985. The In=Ceram crown has a high-strength aluminum core infiltrated with a glass matrix and then is veneered with a feldspathic porcelain. It possesses the highest Lab. strength among the advanced all-ceramic systems. Vita In-Ceram restorations were recommended in single crowns and anterior 3-unit bridge New advancements in In-Ceram make it more versatile and try to cover all fixed prostheses. This article introduced some all-ceramic systems since 1980s and reviewed the Vita In-Ceram system. |
